Potter's decision is unrelated to the fallout over payments from World Cup payments for the Bati players, which has led to threats of a boycott of future Tests and demand for changes at board and management level of the FNRL.

''I had four years in the role and I want to be able to spend more time with my family and more time with the Knights,'' Potter told NRL.com.

''I thought we had a bit of success with the squad and the players really excelled given that we weren't really at full strength at the World Cup with a few guys out through injury and having surgeries. We probably over-achieved, I thought.''

Under Potter, the Bati thumped Italy, United States and Wales before stunning the Kiwis 4-2 in the quarter-final in Wellington. It was the first time that Fiji had beaten a Tier One nation.
